Gia... For a guy?

Gia is the name I thought of for a boy character who is going to be in an upcoming comic of mine. He is a short, black-haired guy who shows very little emotion, and often comes off as depressed. But when I looked the name up on Google I found a site claiming it could be applied to both genders, but when I looked it up here it said that is was a female name. I do like the name, and I do think it would be sort of fitting for my character, and of course since my comic will be a work of comedy there could be some funny gender-confusion problems, but I just wanted to know if it might be a little over-the-top.

I could see it working as a playful nickname for a couple (very) Italian names. Note that it would probably work best if Gia was said the Italian way (Jyah) vs (Gee-ah). You might consider any of the fuller names:

GiacintoGiacobbeGiacomoGiancarlo
Gianfranco
Gianluca
Gianmarco
Gianmaria (if gender confusion is something that you're after, you may want to consider this traditional male Italian name)Gianni (though this is a short form of Giovanni)Giannino (another short form of Giovanni, occasionally used as a full name)
Gianpaolo
Gianpiero
Gionata (another good one for gender confusion, this one is the Italian form of Jonathan)

I think it could work, maybe as a nickname for a longer name such as Giancarlo, but also as a full name. If you want, you can always explain it as "he was named after his grandmother" or something like that.
